Heart failure (HF) is a disease experienced globally by 26 million people. A new EU-funded project will monitor breath, saliva, and other symptoms of HF and send smartphone alerts to HF patients every time they find themselves in a critical situation.

Hannah Kuper, co-director of the International Centre for Evidence in Disability at the London School of Hygiene and Tropical Medicine in the UK, explains how cheap smartphone adapters can be used to diagnose ear and eye conditions. Since over half of the world's population has a mobile phone, this technology, she argues, can ensure patients in all areas get appropriate treatment.  

In the fight against HIV, better understanding of the structure of the virus could lead to new antiretroviral drugs. University of Illinois researchers recently used molecular simulations on the Blue Waters supercomputer to determine the chemical structure of the HIV capsid, which plays a key role in debilitating the immune system.

With current testing methods unable to accurately assess the more than 2 million experiences of concussion in the US each year, advancements in diagnosis and treatment are critical. Revolutionary, high-resolution 'virtual recordings' of electrical currents in the brain could provide a solution.

It isn't easy to make grids user-friendly. Find out what lessons Vincent Breton, lead for the French NGI, learned while developing a system to monitor bird flu in Vietnam.

Feature - Achilles tendon a blessing, not a curse

Compared with other runners on this planet, humans are feeble.
If Olympic sprinters competed against mammals of comparable size, they would never even qualify for the finals. The top speed for an in-shape male human is normally between 15 and 18 miles per hour (24 to 29 kilometers per hour). The world record is 27 mph (43kmh), and that was sustainable for only a few seconds.
Meanwhile, horses have been clocked at about 48 miles per hour, wolves about 42, and the speed champion — the cheetah — at 70 miles per hour. (That’s about 77 kmh, 68 kmh, and 113 kmh, respectively.)
Even warthogs are faster than us.
But in the field of endurance racing however, we leave everyone else in the dust. Over long distances, a well-trained human can outrun a horse.
What is the ke

Feature - RadiotherapyGrid Gamma-ray map for treatment. Image courtesy BEinGRID Cancer is Europe’s second largest cause of death. One of the most common and effective treatments is external radiotherapy, where a Linear Accelerator (Linac) attacks the cancerous tissue with radiation delivered from several different directions. The treatment plan — the direction, size and length of dosages — has to be carefully calculated to avoid damaging healthy tissue. These calculations can take a long time — speeding up this process would allow earlier treatment and more patients to be treated.RadiotherapyGrid is a solution based on grid technology that helps hospitals plan the best possible treatment for each patient. It has two core functions: verification of plans using accurate — but computationally expensive — techniques; and searching for the optimal treatments. These tools improve the efficiency and effectiveness of planned treatm

Feature - Computing a way out of poverty

In the Philippines, the Asian Development Bank and grid specialists are getting together to figure out best investment strategies for Asia’s poorest regions.
One of the outcomes of the EUAsiaGrid Project, funded by the European Commission under Framework Program 7, has been to spark new grid-based collaborations in Southeast Asia.
One example is the result of a meeting that occurred last October, when representatives from EUAsiaGrid partners went to the Asian Development Bank (ADB) Headquarters in Manila, The Phillipines, to explore ways to model the impact of poverty alleviation investments that ADB makes.
In the past, investments by development banks such as the ADB and the

Feature - Cancer researchers speed crystallography

Scientists have trained a system to recognize the formation of 3-D protein crystals, automating a time-intensive, manual process necessary for scrutinizing the structure of cancer-related proteins.

Using the World Community Grid, scientists at the Help Conquer Cancer Project have found a way to automate and speed up protein crystallography, according to a recent paper in the Journal of Structural and Functional Genomics.
X-ray crystallography is the process of using x-rays to map the structure of crystals. Although biological molecules such as proteins and DNA are not normally crystalline in form, they can be prompted to form crystals through exposure to the right chemical compounds. Once crystallized, the scientists can use x-rays to map the protein; knowing the structure of a protein is invaluable to scientists who are trying to understand how a protein interacts with the human

SAFE-BioPharma - A new domain standard for secure identity

In medical and pharmaceutical research, researchers deal with sensitive private information on a daily basis. That makes secure identity management a crucial need. Mollie Shields-Uehling is the CEO of the SAFE-BioPharma Association, a non-profit organization charged with creating a standard that meets that need.
iSGTW: Thank you for joining us for this discussion, Mollie. Could you tell us a little bit about SAFE-BioPharma?
Shields-Uehling: SAFE-BioPharma Association is a non-profit industry collaboration established by the world's leading biopharmaceutical companies to develop and maintain a global interoperable digital identity and signature standard for the biopharmaceutical and healthcare communities. The purpose of the standard is to allow the transformation of business and regulatory process to

Feature - Dealing with dengue

First, you get a bad headache. Then your joints feel like they are being crushed. This is followed by fever and a bright red rash on your legs and chest. You may also start vomiting or have diarrhea. This is dengue fever, and it affects two-fifths of the planet’s population. Thanks to the EUAsiaGrid project, grid technology is doing its part to help reduce the burden of this devastating disease.
For most, dengue fever passes after a very unpleasant week, but for some it leads to dengue haemorrhagic fever, which is often fatal. Like malaria, dengue is borne by mosquitoes. Unlike malaria, though, it affects people in cities as much as in the countryside. As a result, it has a particularly high incidence in heavily populated parts of South–East Asia, where it is a significant source of infant mortality in several countrie

Announcement - US eHealth Collaborative seeks board members
